Colloquial, form of eye crap, the crusy and/or gooey jism that forms in the corner(s) of your eye(s) overnight, at least some times. Not often, but usually after a wild evening. Can be dangerous to rub upon awakeining, you can scratch your cornea. A close relative of mehmeh

I woke up with a serious case of eye-eye. I'm going to knit some mehmeh stockings and make some eye-eye cookies.
